It's impossible to read the first gel. We do it again. In the second gel, we obtain FNR Part I and FNR Part II fragments at the right size. We can purify it. We also obtain BphR2 Part I frangment at the right size but it was mix with other DNA frangments. We will try to make a gel purification of it.

Even if the two lightest stripes are overlapping, aims to do a second gel purification with these two stripes, we did the gel purification . After argumentation, we decided to do the PCR of BphR2 Part I again thanks to new PCR program and new quantities.
